I've been telling reporters that Twitter's new national blocking policy was like Chekhov's gun. Its recent appearance inevitably prefigured its future use.

The issue of press accreditation continues to reverberate. In November, when the Occupy movement came into conflict with law enforcement across the country and at least 20 journalists covering the events were arrested, CPJ reported that disputes over press accreditation were at the center of many of those arrests. Last week, credentials played a role in the arrests of journalists not only at tumultuous Occupy demonstrations in Oakland but also inside the more hushed chambers of Capitol Hill.

Last week, Twitter provoked a fierce debate online when it announced a new capability--and related policy--to hide tweets on a country-specific basis. By building this feature into its website's basic code, Twitter said it hoped to offer a more tailored response to legal demands to remove tweets globally. The company will inform users if any tweet they see has been obscured, and provide a record of all demands to remove content with the U.S.-based site chillingeffects.org.

The Internet doesn't bring freedom. Not automatically, anyway.

That's one of the main messages of Rebecca MacKinnon's new book, Consent of the Networked, which had its New York launch at the offices of the New America Foundation last night. In a conversation with CNN managing editor Mark Whitaker, MacKinnon, a CPJ board member, said it's up to concerned citizens, governments, and corporations to make decisions about how the Internet is used. She contrasted the Twitter-powered revolt in Egypt last year with the "networked authoritarianism" of China, where corporations are collaborators in a system designed to preserve Communist Party rule.

For centuries, journalists have been willing to go to prison to protect their sources. Back in 1848, New York Herald correspondent John Nugent spent a month in jail for refusing to tell a U.S. Senate committee his source for a leak exposing the secret approval of a treaty with Mexico. In a digital age, however, journalists need more than steadfast conviction to keep themselves and their sources safe. Government intelligence agencies, terrorist groups, and criminal syndicates are using electronic surveillance to learn what journalists are doing and who their sources are.  It seems many journalists are not keeping pace.

In "Banding Together: The Chauncey Bailey Project Fights Impunity," CPJ’s Maria Salazar-Ferro describes how a group of Bay Area journalists worked together to ensure that the murder of their colleague did not go unpunished. Using investigative journalism as an advocacy tool, the Bailey Project held authorities accountable and brought about the conviction of the mastermind. (3:05)

When U.S. Secretary of State Hillary Clinton meets this week with Burmese President Thein Sein, opposition leader Aung San Suu Kyi, and senior ranking members of the military establishment, she conspicuously will not have the opportunity to meet with journalist Sithu Zeya.

Sithu was detained by police after recording the impact of a bomb that exploded in a crowded Burmese marketplace in April 2010. The journalist was sentenced to 17 years in prison on charges related specifically to his reporting activities, with an additional 10 years tacked on this year -- soon after Thein Sein announced his intention to increase media freedom in Burma.

Press freedom groups worldwide are banding together today, the International Day to End Impunity, to demand justice for hundreds of journalists murdered for their work. On this day, the Committee to Protect Journalists and dozens of other members of the International Freedom of Information Exchange are remembering journalists killed, and urging governments to take action against those responsible for their deaths. We are also looking for lessons learned in past fights--like the one led by a group of journalists from the San Francisco Bay area, who battled tirelessly to ensure that justice was served in the slaying of their colleague Chauncey Bailey.

As he exited his car and entered the performance center, the man in the dark pinstriped suit caught the attention of a few people, who trailed after him. The small crowd greeted him respectfully and enthusiastically, as someone they felt they had known all their lives. In return he shook hands calmly and asked the names of his greeters. He was veteran television news anchor and reporter Dan Rather.

Rather is this year's recipient of the Committee to Protect Journalists' Burton Benjamin Memorial Award for lifetime achievement in defending press freedom. At an event Thursday commemorating CPJ's three decades of battling for free expression, at the Kennedy Center in Washington, D.C., Rather was interviewed by PBS's Gwen Ifill, where he discussed today's challenges to independent journalism as well as his own career.

New York, November 15, 2011--The Committee to Protect Journalists is concerned by today's reports of New York City police mistreating and detaining journalists and obstructing them from covering events at the Occupy Wall Street protests.
